Sealed Lead Acid Maintenance Free
Technical Featheres
Sealed Construction : SUNNY’s unique construction and sealing technique ensure that no electrolyte leakage can occur from the terminals or cases of any SN batteries. This Feature ensures safe and efficient operation of SN batteries in any position.
Absorptive Glass Mat System : SN batteries make use of fine mat separators (glass fiber) where in sufficient electrolyte in absorbed to provide longest life and steady service. This system prevents escape of electrolyte from the separator which causesleakage.
Gas Recombination : SN batteries incorporate a unique design that effectively controls generation of gas and allows recombination of over 99% of gas generated during the normal use.
Maintenance-Free Operation : During the expected floating service life of SN batteries there is no need to check the specific gravity of the electrolyte, or add water, which means they require no maintenance service.
Position-Free and Leakage-Free : The combination of the sealed construction and the use of absorptive mat separators permits operation of SN batteries in any position without loss of capacity, electrolyte, nor service life. The SN batteries are made to operate in any position.
Low Pressure Venting System : SN batteries are equipped with a safe, and low pressure venting system, which operates at 7 psi to 10 psi, automatically releasing excess gas in the event that gas pressure rises to a level above the normal rate ensuring no excessive buildup of gas in the batteries. Safety valves are automatically released once the pressure is return to normal rate.
Heavy-Duty Grids : The SN heavy-duty lead-calcium alloy grids provide an extra performance and service life in both cyclic and floating applications even in deep discharge condition.
Cyclic Life : Depending on the average depth of discharge, over 1,000 discharge/recharge cycles can be expected from SN batteries.
Float Life : The expected life of SN batteries under float (trickle charge) use is 3 to 5 years.
Low Self-discharge/Long shelf life : At an ambient temperature 20 ํC (68 ํF), the self-dscharge rate of SN batteries is only 3% (approx) of rated capacity per month. The low self-discharge rate permits storage of SN batteries for up to one year without significant loss of efficiency or appreciable deterioration performance.
Operating Temperature Range : SN batteries may be used over a board range of ambient temperatures permitting flexible system design and location.
High Recovery Capability : SN batteries have an excellent charge acceptance and recovery capability even after deep discharge. 881XIBLLM
